Description

[Detailed description of the invention] Industrial application field The present invention relates to a helmet worn when riding a motorcycle, tricycle, etc., and particularly relates to the structure of a visor in a helmet that has a ventilation structure. be.

BACKGROUND OF THE INVENTION In a helmet worn when driving a motorcycle or the like, a liner made of, for example, a foamed resin material is attached to an outer skin made of a hard resin material, that is, an inner surface of a cap body. However, since such a liner has a high heat insulating property, hot air gets trapped in the head, which tends to cause discomfort, especially when used in the summer.

As a countermeasure, a ventilation path is provided inside the cap, and an air guide port for the ventilation path is provided on the front of the cap, and an eave attached to the front of the cap is used to collect the running wind and actively guide the air. A helmet that has a structure that guides the user to the mouth has been proposed.

Problems that the invention aims to solve: However, when the eaves are used to collect air, when driving on an unpaved road, dirt etc. thrown up by other vehicles in front of the vehicle enters the inside of the helmet along with the wind. Foreign matter such as dirt obstructs ventilation and causes discomfort.

Means and Effects for Solving the Problems An object of the present invention is to provide a helmet that can actively collect running air using an eave and prevents foreign matter from entering the helmet.

The present invention provides a helmet which has an eave on the front surface of the cap body and has an air guide port in the eaves attachment portion for introducing running air into the cap body, wherein the eave is attached to the cap body and covers the air guide port. It consists of an eave main body having an air intake for introducing running wind, and a lower wall attached along the lower edge of the eave body, and a wide interior is formed by the eave main body, the lower wall, and the front surface of the cap body around the air intake. In addition to forming a chamber, a wide opening is formed in the area facing the front of the cap body around the air intake opening by the peripheral edges of the eave body and the lower wall, so that when driving, the air intake opening of the eaves flows into the inner chamber. The outside air that has entered enters the cap body through the air guide port of the cap body.

Embodiment Hereinafter, an embodiment of the present invention shown in FIGS. 1 to 6 will be described.

FIG. 1 shows, as a side view, a full-face helmet 10 with an eave 24 attached to the front surface of the cap body 12. As shown in FIG. The cap body 12 is made of a hard resin such as FRP, and has a shock absorbing liner 14 (made of styrene foam, for example) attached to its inner surface. A plurality of ventilation passages 16 are formed in the inner wall of the liner 14 in the form of grooves extending from the front part to the rear lower part of the cap body 12. It communicates with the port 18. A cushion material 20 (for example, made of polyurethane foam) is attached to the inner wall of the liner 14 at a position that contacts the wearer's head. The cushion material 20 covers the ventilation passage 16, and the cushion material 20 includes a plurality of openings 22 communicating with the ventilation passage 16.
is formed so that the air flowing in the ventilation path 16 is blown inward through the opening 22 (see FIGS. 1 and 2).

Further, an eave 24 that defines a wide interior chamber 25 together with the front surface of the cap body 12 is screwed and fixed to the cap body 12 so as to cover the plurality of air guide ports 18 . FIG. 3 shows the attachment relationship, and the eave 24 is fixed by screwing screws 40 into nuts 13 implanted on both sides of the cap body 12. A pair of left and right mounting openings 2 formed in the upper wall 26 of the eaves 24
8 has an oval shape, so that the mounting position of the eaves 24 can be adjusted in the vertical direction.

The detailed shape of the eaves 24 is shown in FIGS. 4 to 6 (however, FIG. 4 is a plan view, FIG. 5 is a view taken along the - line, and FIG. 6 is a sectional view taken along the - line in FIG. 4). The upper wall 26 constituting the eaves body is shown in FIG.
The eave 24 is formed by connecting the upper wall 26 and the lower wall 32 with a rivet 34 along the lower edge of the upper wall 26 to have a V-shaped cross section. A wide opening 41, which constitutes one surface of the inner chamber 25, is formed by the peripheral edges of the upper wall 26 and the lower wall 24 in a portion facing the front surface of the cap body around the air guide port 18. There is. The upper wall 26 has a pair of mounting openings 28 on the left and right sides, and a horizontally elongated air intake 30 on the front side. Further, a cut-and-raised protruding piece 31 is formed on the upper side of the air intake port 30, and the protruding piece 31 allows
Wind from the vehicle is actively captured and guided into the interior chamber 25 through the air intake 30.

For example, when riding a motorcycle while wearing the helmet 10 having the structure described above,
The running wind collected by the protrusion 31 is passed through the air intake 30.
The pressurized air enters the inner chamber 25 through the cushioning material 20, the pressure in the inner chamber 25 increases, and the pressurized air is forced into the air passage 16 through the air guide port 18 and passes through each opening 22 formed in the cushioning material 20. The other part is emitted towards the person's head, and the other part is emitted to the cap body 1 through the ventilation passage 16.
It is discharged from the rear lower end of 2.

In this way, since the eaves 24 that cover the air intake port 18 have the inner chamber 25, even if dirt, mud, etc. enter through the air intake port 30 along with the traveling wind when driving on a rough road, such foreign objects will not be removed. The air loses speed in the inner chamber 25, falls downward and accumulates in the wide inner chamber 25, and the purified air enters the air passage 16 through the air inlet 18. Therefore, it is difficult for foreign matter to accumulate in the ventilation passage 16,
Good ventilation is maintained at all times. Moreover, by forming the eaves 24 into a double structure to define the interior chamber 25, there is an advantage that the internal pressure increases during running, improving ventilation performance.

Note that foreign matter caught within the eaves 24 and accumulated on the lower wall 32 can be removed by removing the eaves 24 as appropriate and washing with water.
0 weight increase can be suppressed.

Effects of the invention In this invention, an inner chamber is constituted by the eave main body (upper wall), a lower wall attached to its lower edge, and the front surface of the cap body, and the outside air flowing in from the air intake of the eaves main body flows into the inner chamber. Since it enters the cap body after passing through the cap body, even if dirt and other particles enter through the air intake along with outside air when driving on rough roads, these foreign objects lose speed in the large interior chamber, fall downward, and accumulate inside the interior chamber. , air inlet caused by foreign matter,
Air flow within the ventilation path is not obstructed,
Clean air flows into the cap and good ventilation can be achieved within the cap.

The inner room has a simple structure with a small number of parts, simply attached to the lower wall of the eave body, so it can be easily manufactured, and a spacious inner room can be easily created without changing the overall design of the eave. Moreover, when the eave is removed from the cap body, the part corresponding to the front of the cap body becomes a wide opening of the inner chamber, so foreign matter accumulated in the inner chamber can be easily removed from this opening. Out.

Furthermore, since the outside air inlet is provided in the eaves body (top wall), there is no need for a special structure for overall reinforcement, and since there are no protrusions formed on the eaves, the eaves can There is no risk of damage caused by.
